Background: Diets rich in fruits, vegetables, and medicinal plants possess antioxidants\npotentially capable of mitigating cellular oxidative stress. This study investigated the antioxidant,\nanti-acetylcholinesterase (AChE), and total phenolic and flavonoids contents (TPC/TFC) of dietary\nsources traditionally used for memory enhancing in Niger Delta, Nigeria. Methods: Dacroydes\nedulis methanolic seed extract (DEMSE), Cola lepidota methanolic seed extract (CLMSE), Terminalia\ncatappa methanolic seed extract (TeCMSE), Tricosanthes cucumerina methanolic seed extract (TrCMSE),\nTetrapleura tetraptera methanolic seed extract (TTMSE), and defatted Moringa oleifera methanolic\nseed extract (DMOMSE); Dennettia tripetala methanolic fruit extract (DTMFE), Artocarpus communis\nmethanolic fruit extract (ACMFE), Gnetum africana methanolic leaf extract (GAMLE), Musa paradisiaca\nmethanolic stembark extract (MPMSE), and Mangifera indica methanolic stembark extract (MIMSE)\nwere evaluated for free radical scavenging antioxidant ability using 2,2-Diphenyl-1-picrylhydrazyl\n(DPPH), reducing power capacity (reduction of ferric iron to ferrous iron), AChE inhibitory potential\nby Ellman assay, and then TPC/TFC contents determined by estimating milli-equivalents of\nGallic acid and Quercetin per gram, respectively. Results: The radical scavenging percentages\nwere as follows: MIMSE (58%), MPMSE (50%), TrCMSE (42%), GAMLE (40%), CLMSE (40%),\nDMOMSE (38%), and DEMFE (37%) relative to....................
